This web site focuses on the history, interpretation, and restoration of John Singer Sargent’s monumental mural cycle, Triumph of Religion, in the McKim building of the Boston Public Library. The murals, which Sargent executed over the course of nearly thirty years (1890-1919), have deteriorated considerably, and their restoration is part of a larger renovation of the McKim building. Partially funded by the Institute for Museum and Library Services (IMLS), the restoration is being carried out by conservators from the Straus Center for Conservation, Harvard University Art Museums.
